This invention relates to cutting machines and is herein illustrated as embodied in a machine designed to triin the linings of.

shoes.

In the manufacture of certain kinds of shoes, for example ladies pumps, it isfcustomary to leave part of the lining projecting above the upper edge of the pump and to tack this projecting portion to the last preparatory to the side-lasting operation so that the linished pump shall fit snugly about the waist ot the foot of the wearer. if no such Lacking is done. the side-lasting operation tends to puli the upper edges of the shanko-r waist portionof the puin-p dowln over the swelling portion of the last so that the sise of the opening for the entrance of th`e feet in the finished pump is increased and the pump is therefore more or less loose on the foot. (Hurnionly the lining is left projecting above the upper et two opposite points in the shank or waist portion of the shoe in the forni of straps about two inches vide, but there is nothing fixed about this procedure and sometimes the lining is left projecting above the entire upper edge of the shoe. Whatever the extent of this roecting lining, it is commonly tacked to t e last by the puller over. and the pump comes to the side laster in that condition. After the side lasting` the remaining operations are pei'- fornied in the usual manner, and not until the pump reaches the finishing room is the projecting lining trimmed ofi'.

In the manufacture of rubbers-it is customary first to fasten the lining to the last or form und then to build thev rubber over the form thus covered. After the rubber is' finished. the lining which projects above it is slit, and then' the rubber is pulled from the torni. Here again a. oertain'amount of siirplis projecting -lining must betrinimed o The generui obiect of the present inve-n tion isto provide a machine for performin f trimming operations such as those whic` have been referred to above. To this end the illustrative machine is rovided with a support adapted to enter t e shoe in such manner as to erniit the upper edge of the shoe to be fe over it and with a reciproeatingl cutter for severing the projecting lining. The support is inclined to the path of movement of the cutter so as to cause the lining to be severed on an an fle and is provided with a shear blade with which the cutter cooperates, the purpose of the angular relation being to ensure that the upper edge of the severed liningshzill be concealed from view and that of the shear blade that a clean cut shall be inside.

Commonly in pumps the lining and the upper are stitched together close to the upA per edge of the slice so that it is desirable in order to produce good work, to spread them apart as much as possible bci-'ore` trimming the lini To this end e separator is provided whie runs in the crease between the lining and upper and serves to bend the lining sway from the upper just. in front of the cutter, the separator, in the illustrative inaehineybeing formed so as to perform the further function of a cutter guard.

These and other features of the invention including certain details of construction and combination of parts will be descrihed as embodied in an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying drawin ig'ure 1 is an end elevation of a machine in which the present invention is embodied;

Fig. 2 is a vertical longitudinel section of a portion of the overhanging Vfirm which Supports the. operative parts;

ig. 3 is a perspective of the-separator,

the cutter, the support and the presser, and

Fig. 4. is an end elevation of the sinne parts on an enlarged scale showing a, piece of work in process of being operated upon.

The arts of the macliinewhich operate upon tie work are mounted at the end of an overhanging arm 7, which. is piirt of the l frame, said arm carrying a drive shaft 9 fast to the outer endof which is a cuni 11 having cut therein a track 13. The rear end of the sha-ft carries a pulle i which may bey driven continuousl)r by a be `t 15* erticnliy slideble in suitable bearingein the outer emi 11a l 39 and with the ,2 it will be seen that the of the arm is a cutter-bar 17 the upper end of which is fastened by screws 19 to a verticall reciprocating block 21,. Horizontally sli( able in a bore in this block is a rod 23 havin r at its inner end a roller 25 which is adapted to run in the cam track 13, a spring 27', fast at its outer end to a finger 29 held rigid with the rod and at its inner end to the block 21, servingr to urge the rod toward the cam and to ho d the roller 25 in the cam-track. A second sprin 31, fast at its lower end to the block 21 and at its up er end to the stationary arm 7 exerts at al times an upward pull on the block 21 so that when, as will presently be explained, the rod 23 is pulled out to disenga e the'roller 25 from the camtrack 13, the b ock 21, and with it the cutterbar 17, is raised. In order to facilitate such withdrawal of the roller 25 to disconnect the zobutter-bar from its driving cam and to per mit the ensuing upward movement of the cutter-bar, a lever 33 'very loosel fulcrumed at 34 and extending through a s ot 35 in the hollow arm 7 is arranged to contact `with an ggright pin 37 which is screwed into the rod and extends up throu h a vertical slot in the block 21. By regarring to Figure slot 35 basa horizontal and a vertical ortion. In the position of parts shown, t e roller 25 is located in tbe camtrack 13. If now the lever 33 is swung to the ri ht-hand end of the hori zontal portion o the slot 35, the roller 25 will be withdrawn from the cam-track 13 against the force of the spring 27; and, if

the lever is then released, the spring 31 will I lift the block 21 and cutter-bar 17 until the lever 33 contacts with the upper end of the vertical portion of the slot 35. By this mechanism the cutter 39 may be thrown into or out ofV operative position when desired and may likewise be connected with or dis connected from its drivin mechanism.

This cutter is adjusta ly fastened by screws 41 to a small block 43, there being a slot in the cutter ,so that it may be adjusted vertically; and the block is ,horizontally ad- ]ustable on the cutter bar 17 being held in adjusted posltionfby a screw 45, which passes through a slot in the block and is threaded into the bar. The cutter is in the form of a knife havin a cuttinlg edge indicated at 139 and. a gul e' 239. ocated approximately beneath the cutter is a work `suporting member 47, formed at the lower end of an arm 49 which is bolted to the main arm 7. This member has an extension in the form. of a plate 147 adjustably fastened in place by screws 51 which pass through slots in the plate. A hardened' block 247 set into the member 47 has formed thereon a shear blade whichcooperates with the edge of the cutter guide 239. It will be understood that the work to be operated upon, rests upon the registering faces of the lower part of the arm 49, the shear block 247 and the plate 147 which form together the work support. The operative face of the work lsupport is thus inclined to the x,lane of the cut of the cutter.

Located in front of the cutter-nt .the

right as viewedin Figure 1- is a combined lining-separator and cutter-guard. The lower part of this member is right-angled 1n cross-section, one portion being in the forml of a plate 53 having a beveled lower end shaped to run in the crease between the lining and the upper 200 close to the line of stitches 300 b which the two are jolnted in a ump. his plate 53 is substantially para] el to the cutter, its function being to separate the lining and the upper by bend.

ing the lining awa from the upper as shown in Figure 4. It a so aids in't e guiding'of the work and serves as a guard for one side of the cutter, `The portion 153 also in the form of a plate, guards one en of the cutter. This member, which for brevity. will A hereinafter be referred to in its entirety as a cutter-guard has at its to a right angled extension which is adjusta ly fasteny i 63 tending v its lower limit of movement, said limit being determined by a set'screw 65 which may be held in adjusted position by a lock-nut. n order to permit raising and lowering ci. the cutter-guard, there is clamped to the b lr 55 a co'llar 69 having thereon a Projecting in 71 with which a bell crank li ting lever 733 may be caused to contact. This lever is Eivoted at 75 to the arm 49 and is normally eld in the position shown by a spring 77. This pin 71.is also made use of Vto raise the cutter-guard when the cutter is raised in the manner which has been described above by manipulating the lever 33. lVhen this latter lever is man1 ulated to raise the cutter-bar, the end of t e screw 45 strikes the under side of the pin 71 so that the cutter-guard is raised when the cutter is raised.

In order to hold the work on the worksupport there is rovided a presser foot in the form of an id e roller 79 which is carried by a bent stem 81, the upper end of the stem being fastened to the lower end of a bar 83. The bar 83 is similar to the bar 55 and is similarly mounted. Fastened to the bar 83 is a vertically Slidable block 35 the lower limit of which is determined by the position of the screw 87, a spring HS) serving at alll times to urge the bar 83 downwardly. In order to permit the presser to be raised when desired, a finger hold 91 is fastened to the stem 81.

Referring ugainito the guard 153, it is iti desirable under certain circumstances, fo'r example when a Aseam 1s encountered, to

raise the guard independently of the knife.` mi 'Ln-such case it is desirable that the guard should not be raised high enough to A rmit the edge of the upper to be crowded lneath it and come into contact with the knife, To this end there is threaded into the arm 49 an adjustable stop-screw 50 into the stein of which is threaded an expansion screw 52 to hold the stop-screw in adjusted position. I and locked in such a position that when the lever 73 is rocked about its pivot until the adjacent arm of the lever contacts with the head of the screw, the guard will be ifted enough to permit a seam to pass beneath it without dragging but not enough to ermit the edgeof the upper to pass beneath 1t. In this general connection 1t should be understood thatthe gua rd or separator should not at anjr time exert any' considerableA drag upon the work and that the proper normal position of the guard is secured by adjusting the stop-screw which limits the downward movement of the ard dueto the action oi the spring 63. y roviding the stop-screw 50, the proper rcation of the guard to` the work-may be secured when n seam is encountered.

Assuming that the roller 25 is located in .the cani-track 13 and that the' shaft 9 is rotating, the operation of the machine is as follows: The shoe is tilted at an angle and the work support caused to enter it.' cutter-guard and VLarilv raised ,and then lowered to permit the work to assume the position shown in Fig. l with the separator plate53 running. in the crease between the upper 200 and the lining lf2() and the presser foot engaging the edge of the upper. said edge usually being beaded-y es shown. 'l he shoe is then fed over'the support,

lining on a bevel close to the line of junc-4 ture of the upper and the lining one line slightly below the levei of the edge of the upper. It is desirable, as, has been explained, if a seam is encountered, to raise the cutter'guard; and this may be doneaccurately by manipulating the lever 7 3 until it contacts with the stop-screw .50.

Although the invention has been set forth as embodied in a particular machine it should be understood that the invention'v not limited in the scope of its application to the particular machine which hasr been shown and described.
